IMPROYEMENT IN SPOKE-TENONING AND FELLY-BORING MACHINES.

Specification forming part of Letters Patent N0. 200,598, dated February26, 1878 application filed September 3, 1877.

To all whom it may concern:

Be it known that we, H. S. BARNES and JOHN I. MILLER, of West Point,county of Columbia, and State of Wisconsin, have invented an ImprovedSpoke-Tenoning Machine.

The following description, taken in connection with the accompanyingplate of drawings, hereinafter referred to, forms a full and exactspecification, wherein are set forth the nature and principles of theinvention, by which the same may be distinguished from others of asimilar class, together with such parts thereof as are claimed as newand are desired to be secured by Letters Patent of the United States.

Our invention relates to that class of machines which are made use offor forming tenons on the outer ends of spokes, and also for boringfollies; and the nature thereof consists in certain improvements in theconstruction of the same, hereinafter shown and described.

In the accompanying plate of drawings, in which corresponding parts aredesignated by the same letters, Figure 1 is a plan view, showing thespoke-tenonin g machine with the fellyboring attachment combinedtherewith. Fig. 2 is a side elevation, showing the spoke-tenoningmachine with the folly-boring attachment removed therefrom; Fig. 3,longitudinal section; Fig. 4, perspective view of folly-boringattachment; Fig. 5, end view of two frames.

The general construction and operation of the machine are obvious fromthe drawings.

A A designate two flames, longitudinally slotted for the reception ofthe spoke. The upper frame A is vertically adjustable, and is operatedby the screws a. B is the shaft, which is rotated by the crank 12, andprovided with a collar, 01, secured in position by a set-screw, for thepurpose of gaging the depth of the tenon cut by the hollow auger G.

The boxes D, in which the shaft revolves, are arranged to slidevertically in the frame, and are attached to the longitudinal frame E.They are rendered vertically adjustable by the screws 0 and the springF, arranged between the said frame E and the bed-plate H of the machine.7

The said hollow auger O is rendered selffeeding by means of the spiralspring 71., arranged upon the shaft B. The said shaft is forced backfrom the spoke by means of the lever I, having a beveled side, whichcatches in notches cut on the curvilinear support K, and is thereby heldin position. The short arm of the said lever is pivoted to sleeve m uponthe said shaft.

M designates the felly-boring attachment, consisting of the vise-blockm, having a slotcut thereon, by means of which it is fitted upon thebase-plate. The felly is clamped in place upon the vise-block by meansof the screw, which actuates the clamping-piece N.

Having thus described our invention, we claim and desire to secure byLetters Patent of the United States v A combined spoke-tenoning andfolly-boring machine, consisting of the frames A A, screws a, shaft B,collar d, hollow auger 0, boxes D, frame E, screws 0, springs F and h,lever I, and felly-boring attachment M, all combined and operatingtogether as and for the purposes described.

In testimony that we claim the foregoing we havehereunto set our handsthis 236. day of June, 1877.
